'[0 (LZZ whom, it may concern:

-Be it known that I, (has Q. SELLERS, a citizen of the United States,residing at VVellston, in the county of Jackson and State of Ohio, haveinvented a new and useful Lubricating- Wheel, of which the following isa specification.

'This invention relates to wheels having means for automaticallylubricatin the axles upon which they rotate, and has for its objeettoimprove the construction and increase the elliciency of devices of thischaracter.

\Vith these and other objects in view,whieh will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corre sponding parts are denoted by like designatingcharacters, is illustrated the preferred form of the embodiment of theinvention capable of carrying the same into practical operation.

Figure 1 is a sectional view of the hub portion of a wheel with theimproved devices Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3is a perspective view of one of the resilient stop-rings detached.

The improved devices maybe embodied in any of the various forms ofwheels which have axle-openings and rotate upon their journals or axles,but is more particularly de signed for use in connection with mining-carwheels and wheels employed upon similar vehicles and for the'purpose ofillustration is shown ap lied to the hub portion 10 of a wheel of t isclass. i

A continuous -oil chamber or reservoir 11 is formed around the hubsubstantially concentric with the aXle-opening and with one or moreapertures 12 between the reservoir and the interior of the hub, theapertures being preferably provided with the sides converging toward thereservoir.

Formed in the interior of the hub 10 are annular channels 13, spacedapart at opposite sides of the apertures 12 and preferably 10- conformto the interior of the hub and of the axle-journal l6.

Disposed within each of the casings is a wick (represented at 1'1") withone end projecting through the open end of the casing and into theoil-reservoir.

Disposed within the channels 13 are divided rings 18 of resilient metal,such as steel, each ring being provided with a lining 19 of flexiblematerial, such as felt, and placed in its corresponding channel in thehub before the axle is inserted.

Projecting from the outer face of the por tion of the wheel forming theouter wall of the oil-reservoir is an inletcha1nber 20, communicatingwith the reservoir at 21 and with a threaded plug 22 in one end having alongi- ,tudinal aperture 23 and against whose inner end a valve 24 isseated and yieldably maintained in position by a spring 25.

When the reservoir is to be filled, the spout of an oil-can is insertedin the open end of'the plug, which displaces the valve'and permits thereservoir to be filled, and as soon as the spout is withdrawn the valveis automaticall closed and prevents leakage of oil.

The axle 16 is slightly tapered at the outer end, as at 26, tofacilitate its entrance into hub and to enable it to pass the protrudingfelt stop-rings 19 when being inserted. To assemble the parts, thecasings 13, having the wicks 17 therein, are inserted through theaxle-opening into the apertures 12 and the divided rings. 18 19 sprunginto the channels 13, the expansion of the members 18 holding the ringsin position with the felt portions protruding into the interior of thehub for a short distance, as before stated. The journal 16is theninserted, the tapered end 26 passing the felt members and compressingthem into the channels, the journal also assing the casings 14 andcompressing them 1nt0 the inclined apertures 12. The holdingpin 27 orother fastening means is then applied to hold the wheel in position.

The wicks 17 absorb the oil and feed the same slowly to the journal oronly so fast as the oil will be utilized to maintain the jour naleffectually lubricated, but with no surplus flow or waste.

The resiliency of the ring members 18 maintain the felt members pressedclosely u on the journals in addition to the natural e asticity of thefelt, so that none of the oil can pass beyond the hub and drip upon thewheels or track. The device is simple in construction, effect- IIO ivein action, and can be inexpensively manufactured and applied to variousforms of Wheels.

Having thus described the invention, What is claimed is I 1. A hubhaving an axle-opening, an oilreservoir adjacent to and communicatingwith the axle-opening by a dovetailed aperture, a closure for theaperture conforming to the interior of and roportioned to be insertedthrough the ax e-opening, and a fibrous material filling the aperturebetween the closure and reservoin 2. A hub having an axle-opening, anoilreservoir adjacent to and communicating with the axle-opening, by adovetailed aperture with its larger end opening into the axleopening, acorrespondinglyshaped casing adapted to engage the aperture and having aperforate end closing the opening'and curved to form a continuation ofthe adjacent curved Walls of the axle-opening, and a fibrous materialfilling the casing between't-he perforate closure and the reservoir.

3. A hub having an axle-opening, an oilreservoirsurrounding the axle-oening and substantially concentric therewit and with a tapered apertureconnecting the axle-openmg and reservoir with its larger end openinginto the axleopening, a casing proportioned to be inserted through theaxle-opening into and to fit the aperture and having a perforate endclosing the a erture and coinciding substantially with t e interiorcurvature of the axle-opening, a wick engaged within the casing andhaving one end in contact with the erforate closure and the other endextending into the reservoir, a charging-chamber provided with acharging-opening and communicating with the reservoir, and a valve forthe opening. a

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses. OTIS Q. SELLERS.Witnesses:
